Hooper Dam dam
Hooper Dam
Hooper Dam, located in Dodge County, Nebraska, was completed in 1976 by the USDA NRCS with the primary purpose of flood risk reduction along the Elkhorn River. This Earth-type dam stands at 31 feet in height, with a hydraulic height matching that measurement. The dam spans 350 feet in length and has a storage capacity of 19 acre-feet, serving as a crucial structure in mitigating flood hazards in the area.
Managed by the local government, Hooper Dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. With a high hazard potential, the dam has been assessed as satisfactory in terms of its condition as of the most recent inspection in September 2020. While the dam does not have spillway or outlet gates, its presence significantly contributes to the protection of the surrounding community and the management of water resources in the region.
As a key component in the flood risk reduction efforts along the Elkhorn River, Hooper Dam plays a vital role in safeguarding the local area from potential water-related disasters. With a strong foundation and satisfactory condition, this structure stands as a testament to effective water resource management and climate resilience in Nebraska. Its presence highlights the importance of strategic infrastructure in addressing the challenges posed by changing weather patterns and increasing water-related risks.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Hooper Dam
Where does the data for Hooper Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
